This library was generated with [Nx](
# Setup for Alternate Theming
## Running unit tests
## Prerequisites
Run `nx test utils-theming` to execute the unit tests.
- Install @psu/components, @psu/utils, @psu/palette
- Install node-sass and node-sass-tilde-importer as Dev Dependencies
- Application must be setup to use scss and recommended to adhere to the following scss styling structure
- If not already existing, you must have the following files within the src directory at the **_root of the application_**
- `_app-theme.scss`: Import all application, internal application libraries, or external libraries that have theming here and include them within a mixin named `@mixin app-theme($theme)`.
- `_theme.scss`: Set up the primary application theme variables here. This file should import the theme palette from `@psu/palette` and set up the base theme colors. It should follow the structure from the snippet below
@import '~@psu/palette/beaver-blue';
// Setting Theme Colors
$primaryPalette: mat-palette($primary, 700, 50, 900);
$secondaryPalette: mat-palette($secondary);
$errorPalette: mat-palette($error);
$appBackground: #f5f5f5;
- `_typography.scss`: Set up the application typography variables here. Follow the structure from the snippet below. More information can be found in the [typography section]( of the theme utils readme.
// Setting Typography for all themes
$titleFont: 'Roboto Slab';
$bodyFont: 'Open Sans';
$titleRegularWeight: 400;
$titleBoldWeight: 700;
$bodyRegularWeight: 400;
$bodyBoldWeight: 600;
- Import each of the above files into `styles.scss` and follow instructions for [theme generation]( and [typography generation]( from theme utils readme.
## Application-Specific Setup
1. Copy the following snippet into a new file named `` and place in the `tools` directory. The tools directory should be located at the root of the project.
echo Building custom theme scss files.
# Get the files
FILES=$(find apps/ui/src/assets/alternate-themes -name "*.scss")
for FILE in $FILES
$(npm bin)/node-sass --importer=node_modules/node-sass-tilde-importer $FILE > $DEST_PATH/$BASENAME.css
echo Finished building CSS.
2. Create the `alternate-themes` directory at the path `apps/ui/src/assets`. This is where you will add your alternate theme scss files. These scss files should follow the following structure:
@import '~@psu/theme-lib/md2/md2'; // Import the theming utilities
@import '~@psu/palette/nittany-navy'; // Import the alternate theme palette
@import '../../app-theme'; // Import the app-theme mixin to propagate the alternate theme to all angular material, application, and library components
// Setting Theme Colors
$primaryPalette: mat-palette($primary, 700, 50, 900);
$secondaryPalette: mat-palette($secondary);
$errorPalette: mat-palette($error);
$appBackground: #f5f5f5;
// Generate the new alternate theme and propagate it to all components
$theme: generate-material-light-theme(
@include angular-material-theme($theme);
@include app-theme($theme);
3. In the `angular.json`, add the following code to the assets array of the application's build object. Path should be close to: `projects`
"glob": "*.css",
"input": "apps/ui/src/assets",
"output": "./alt-themes/"
4. Add the `build-themes` script to the package.json and update existing scripts to call that script first.
5. Add the `STYLE_MANAGER_CONFIG` to `app.module.ts`'s providers array. Ex:
useValue: [
name: 'beaver-blue',
primary: '#316cae',
isDefault: true
name: 'nittany-navy',
primary: '#143372'
name: 'dark',
primary: '#0d0d0d',
isDark: true
